ILLUMINATING APPARATUS.

Specification of Letters Patent.

Patented Jan. 22,1907.

Application filed August 24. 1904. Serial No. 222.004.

ed to illuminate inclosed spaces and to be inv closed by transparent material, andsome of the objects of the invention are to provide an apparatus ofthis general character which will be simple and cheap in construction and elficient for the purpose intended. v

It is also an object of the invention to provide a circulation of fluid through the apparatus to prevent injury to the contents of the structure illuminated by reason ofthe heatv generated by the illuminating devices. l

It is also an object of this invention to provide an illuminating apparatus constructed to receive `any number of illuminating devices and wherein such devices are adjustably mounted.

Still another object of the invention is to provide an illuminatin apparatus capable of use with an all-glass Slow-case and one requiring no adjustment to the show-case or show-window.

Furthermore, an obj ect of this invention is to produce an illunnnating apparatusV constructed to be readily attached and disassembled in order to increase or renew the illuminating devices.

With these and other objectsin view theinvention consists, essentially, in the construction, combination, and arrangement of parts, substantially as more fully described in the following specification and as illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is an enlarged perspective view,

partly broken away, il ustrating an alllass show-case for which the invention is ilustrated as applied. Fig. 2 is a detail view, partly broken away and partly in section, of

a portion of the apparatus. Fig. 3 is an elevational view of the construction shown in of the end portionsand connections to the apparatus. Fig. 8' is a detail view of a clamp or bracket-employed, and Fig/9 is an enlarged detail view of a; modificd form of the construction illustrated in Figs.I 4 to 7, inclusive. Y

Referring to the drawings, and particularly to thev construction illustrated in Figs. 1, 2, and 3 thereof, reference character 1 desvignates the base or bottom portion of a showcase of any desired construction, but preferably having the upper portionY constructed entirely of glass or transparent material 2, substantiallyv as illustrated in Fig. 1 of the drawings, although it will be understood that this invention is 1n no wise limited to an allglass show-case) or show-Window, as it may e employed withy show-cases or show-windows constructed only partially of glass or other transparent material.

. When used with an all-glass show-case, the

actuatingdevice or motor 3 may be mounted in the lower portion of the case or under the floor, as may be found desirable in practice, and the motor 3 may be suitably connected with an exhausting device or blowin apparatus 4, so as to drive the latter an either exhaust or force the fluid, preferably air, through the illuminating apparatus in order to keep the same cool and prevent the heat from the illuminating devices or lamps from injuring the show-case or its contents, which usually results with illuminating devices now 'in use.

In all-glass show-cases are preferably vertical corner-rods5, Fig. 1, or if these rods are not in use they can be readily vsecured in the base orbottom portion 1 of the show-case, lsubstantially as illustrated in Fig. 1 of the drawings, and secured thereon are brackets or clamps 6, Figs. 1, 2, 3, and 8 constructed to receive the end tubes 7 and to be clamped thereon by the set-screws or other devices 8, substantially as shown, and the end tubes 7 preferably extend beneath the bottom of the showcase, and one thereof is desirably connected to the exhausting or blowing device 4, (shown at 9, Fig. 1.) Upon the end of the tube 7 are movably mounted cap-pieces or holders 10, constructed to removably receive a cylindrical device or tube 11, preferably constructed of transf parent material, and a reflector or partial Fig. 2. Figs; 4, 5, 6, and 7 are detail views 1 shield 12 may be mounted uponthe tube 11 therein, as Well for the purposeof directing'the rays of light i into the show-case and upon the articles as preventing the light 'from being directed into the face` of observers of thecontents of the show-case, although this invention is not limited to use with this relector or shield 12.

Within the caps or end pieces 10 are preferably secured, by means of screws 13 or otherwise, insulating blocks or pieces 14, upon which are mounted spring contact clips or devices 15, constructed to detachably receive the extremities 16 of the guide-rods or conductors 17, the opposite ends whereof are removably`mounted in openings or` recesses in opposite block 14, and on the guide-rods or conductors 17 are slidably mounted strips or devices 18, carrying incandescent or other illuminating devices or lamps 19 and also contact fingers or strips 20, which bear against or contact with the guide or conducting rod 17 and close the electrical circuit therethrough and through the electrical conductors 21, connected with said contact-clips 16 and with the source of'electrical supply.

Referring to the construction shown in Fi 9 of the drawings, there is illustrated a modlied form of' that hereinbefore described and shown, wherein there is a double casing 23, having recessed ends 24 constructed to receive a strip 25 oi transparent material, and the interior 26 is referably recessed, as at 27, to receive the siding device 18, as. will be readily understood by those skilled in the art to which this invention appertains.

It is not desired to limit or confine this vention to the speciiic construction, com ination, and arrangement of yparts herein shown and described, and the right is reserved to make all such changes in andmodifications of the same as come within the spirit and'scope of this invention.

I claim- 1. An illuminating apparatus. provided with an inclosing portion, a plurality of adjustable illuminating devices therein and connection between the latter andthe source bf electrical supply.-

2. An illuminating apparatus ha a tubularv portion, illuminating devices slidably mounted therein and .electrical connection between said devices and the source of electrical supply.

3. .An illuminating apparatus provided with a tubular portion, guide-rods therein, illuminating devices on said rods and connection between said rods and the source of electrical supply.

4. An illuminating apparatus provided 'with a translucenttube or cylinder, illuminating devices slidably mounted therein, and

electrical connections between said devices and the source of electrical supply.

5. An illuminating apparatus provided with a tube, guide-rods therein, illuminating devices slidably electrical connection between said rods and the source of electrical supply.

6. An illuminating apparatus provided with a tube, illuminating devices therein having electrical connection and means for ventilating said tube.

7. An illuminating apparatus having illuminating devices provided with electrical connections inclosed in tube or casing, pipes in each end of said tube or casing and means for eiiecting the 'circulation of air through said y pipes and tube or casing.

8. An illuminating apparatus provided Witha tube, caps for the ends thereof, illuminating devices in the tube for the electrical connection and means of engaging said caps to sup ort the tube.

9. y illuminating apparatus provided with a tube, illuminating devices mounted therein, guide-rods carrying said devices, electrical connections between said rods and the source of electrical supply and means for supporting the tube.

10. An illuminating apparatus provided with a tube, illuminating devices mounted therein, guide-rods carrying said devices, electrical connections between said rods and the source of electrical supply and means for .sup .orting and effecting the ventilation ofv sai tube.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, county of Los Angeles, State of California, this 13th day of August, 1904.
